Embodiment 1
[0062] The SCR flue gas denitrification device of the cement kiln is arranged downstream of the C1-level cyclone preheater (that is, the high-dust arrangement), and the flue gas entering the SCR reactor is 10000Nm 3 / h, smoke concentration 60-80g / m 3 , the temperature is 300-340°C, the SCR reactor is arranged vertically, and there are 5 layers of catalysts in total. The upper part of each catalyst layer is equipped with a steam soot blower, the steam is led from the waste heat boiler, the steam temperature is 340°C, the gas source of each sonic soot blower is controlled by an electric valve, and the purge hole of the rake steam soot blower is 400mm away from the upper surface of the catalyst. A sonic sootblower is arranged on the upper part of the rake sootblower. The center line of the bell mouth of the sonic sootblower is 750mm away from the upper surface of the catalyst. The air source of the sonic sootblower is compressed air, controlled by a solenoid valve, and the compre...
